A couple of general KY questions, as I now primarily work in the Lexington area and am being reacquainted with it:
* Billboard regulations: I always thought billboards had to be located no less than 500' from interstate ROW (and I don't ever recall seeing any billboards along KY Parkways). But just north of London along 75, there are a whole bunch of billboards a lot closer than 500'. I think there is a similar situation on 64 just east of Cannonsburg. Do county regulations trump state regulations regarding billboards?
* Reflectors: I've always been a reflector geek at heart since I tend to do a lot of driving at night. It seems KY is now using what I consider to be a "new old" style of reflector. They've gone back to the old rectangular divots, but they're about 1.5 times longer than before, tapered at both ends, and contain (2) standard snowplowable reflectors spaced about 6-9" apart. The result is just about the brightest reflector I've ever seen, and since they're combining two distinct snowplow-proofing techniques, they might just last as long as the pavement itself. So far I've seen these on a stretch of I-75 b/w north of KY 418 and Man O' War, I-64 in Bath Co near Owingsville, US 27 in the Camp Nelson area (can't remember if N or S of the Kentucky River bridge), and I think the most recently completed 6-lane widened portion of I-75 b/w Lexington and Cincinnati (Williamstown area probably).
Overall I think KY's roads have certainly improved by leaps and bounds since 10 years ago when I last had to drive around there for work. Better signage, more resilient pavement with periodic crack sealing (annoying to look at but it's a proven method), a higher speed limit (they were 65 till 2007 I believe), and excellent media reps who ought to be paid more!
